Why is Rythm Box listening on 2 different ports?


I am showing rythm box listening on one closed port and one public port. I am trying to learn something about ports and networking, so I am a beginner at this. Using a Lenovo el cheapo computer.

netstat -tulpn
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:3689 0.0.0.0:* LISTEN 10293/rhythmbox
tcp 0 0 127.0.1.1:53 0.0.0.0:* LISTEN -
tcp 0 0 0.0.0.0:631 0.0.0.0:* LISTEN -
tcp6 0 0 :::3689 :::* LISTEN 10293/rhythmbox

Also let me know if I just posted too much port info. Many thanks

i can think of a dozen reasons why a bloatware media player would want to listen to something on the internet.
a quick search:

Wasn't aware that it was bloatware nor that it was from Mozilla. Thanks for the info.

It is listening on only one port i.e 3869. The 0.0.0.0:3689 means its listening for all IPV4 addresses and :::3689 is listening for all IPV6 addresses. 10293 is the PID i.e. running process ID of rhythmbox. If something was "talking" to rhythmbox you would see real numbers for the foreign address 0.0.0.0:* like 192.168.0.215:60123.

Code:
Proto Recv-Q Send-Q Local Address Foreign Address State   PID/Program name
tcp    0     0      0.0.0.0:3689  0.0.0.0:*       LISTEN  10293/rhythmbox
I'm not familiar with how DAAP works but as previously posted it uses port 3689. Basically you can listen and share music with other rhythmbox users as well as other DAAP compatible software like iTunes. Music sharing can be disabled.

Here is something that explains how TCP connections work.
